Network Topology

This section shows how our severs are interconnected or connected to the outside world.

Network Architecture

Following diagram shows overall network architecture. and are round robin dns entries. They are populated based on geoip information. For example, for North america they get a pool of servers in North america. Each of those servers in dns is a proxy server. It accepts connections using apache. apache uses haproxy as a backend, and in turn some(but not all) services use varnish for caching. Requests are replied to from cache if varnish has it cached, otherwise it sends into a backend application server. Many of these are in the main datacenter in phx2 and some are at other sites. The application server processes the request and sends it back.

Application Layer

This is a generic view of how our applications work. Each application may have its own design, but the premise is the same.
